Sis
Details & Exclusions
Access here is sold by duration rather than by site, so the trial opens the same catalogue as the lifetime plan. There is no second membership worth buying inside this family.

About Sis Discounts
As a roleplay series in the family, Sis sits inside the VIP4K lineup and shares its billing model exactly. What the series share is all-series access on every tier, plan-based discounts, and no type-in codes anywhere.
The trial at $1.99 removes the risk and the yearly plan removes the cost: Compared with paying $24.99 every month it saves roughly $210 across a year. Above those sits the lifetime plan at $249, paid once and used indefinitely.
One membership covers the whole lineup. That is stated on the plan selector and it matters when comparing against sites that sell each series separately, because the figure you see already includes everything.
Members choosing between brands should know the discount does not move: Bufu, Old4K and Daddy4K all sell the same trial, monthly, quarterly and annual tiers, so pick on catalogue rather than on price.
Sis being a roleplay series in the family means the library has a clear focus, so the honest question is how long you want it rather than which code to hunt.

Sis Promo Code FAQ
What is the best Sis discount right now?
For value, $89.95 a year works out to $0.24 per day; for permanence, $249 lifetime. Both verified weekly.
Do I need a Sis coupon code?
No. There is no code field on the membership panel; pricing loads with the link you arrive through.
Does one plan cover all the series?
It does. The plan selector states that each tier covers all series, which is why the pricing sits above typical single-site rates.
What happens after the three-day trial?
$1.99 opens a limited trial, which is the cheapest way to judge the series before choosing a longer term.
Is the lifetime plan worth it?
It pays for itself against monthly billing in roughly ten months, and against the yearly plan in under three years. After that it costs nothing.
Which plan should I pick?
The break-even is quick: four monthly payments already cost more than the entire year, so a season of use points straight at the annual plan. The same tiers apply on Daddy4K, so the comparison carries across the group.
